,Thisinventionirelates 'to an improvement in =bol1 weevilre xterminating machines.

The object of ;the invention `is to furnish -a meansofnprotection against boll sweevls\ or {53 other ;nsects which :tend -to destroy the r cotton, particularly during its ;bndding zperiod, and in the case of :anepidemicalready havin set in, this invention will prevent itssprea ing.

Among: many :advantages of this machine, :the following maybe mentoned as the principal ones: r

sEirstz to ;gather the ;fallen cotton flower 'which aalread y hasbeen damag-ed :and which may contain the insect,-.-thus preventing 2 the 'spreadinggof-;anepidemic; v

::Second to gather the-maturebollweevils by` meansof oilpans orthe like ;wand

Third to apply ,a posonous; solution of la .suitab1elinsecticide orthe like: eflectively :and

directly to the plant. In the-aecompanying ,drawings Fig.. 1 is a horizontal sectonal view `throughthecon-plete machine; ;Fig. :2 :is arear elevation-of :the same;

depending portion 7 at the rearend thereo for a purpose hereinafter tobe described.

[An elboyv 8 is attached to eachof the'box likecasings (inearjthe top thereof, with its open end turned downward, andhassecnred ;thereto a .flexible tube 9, which in turn attached thereto tubeslO andll telescopicaily ,fitted together so that the lowerinostftuhe may be raisedor lowered, and this colleotor tube 11 is normally-held in elevated pqi- I\ tion by means of s'prings stirrupljis attached to the inner sde of each of the gollectortbes ll'jcojreceiethe ;foot of theoperator ,forj raising and IOWeringthe pollect or mbes as the machi e fis i propll .o m ye ..alo g om E' and extending io 'ia n al yjthropghgah of the) box-like; casings 6 'is a. r Conduit 14 which bybelts 2.0 fro e mo o cxa sourc #of the box lile J EXfendng ra w ar ly fr m rea fan' qa i ing .1 62 c arg 1b 22, hich ext nd thereof.

As a m ns- I l t ng a entr llng the discharge ,rom the jan: oasing lfla gate 1- or vane 28 is disposed therein and is preferably perforatecl or reticulated so as to allow a constant draft of air through the elb-cw 27,

while yet not allowing the collected flowers to pass therethrough, the latter being blcwn out through the tube 22. This vane cr gate 28 i may be controlled by a suitable lever 29, which I the 'machine to direct the flowers or plants between the elbows 27 and between the lower portions 7 of the box-like casings 6. These guides 30 are provided with vertical slots 31 therein for receiving and through which the elbows 27 extend, and are adjustably mounted for different elevations.

Disposed ineach of the elbows 27 is a fanshaped spray nozzle 32 adapted to spray the fluid insecticide onto the flowers or planit-s as the machine passes along a row, which fluid is supplied through a pipe 33 from a tanl: 34 mounted upon the box-lilce casing 6. The supply of insecticide is controlled by means of a valvev 35 regulated hy a control lever 36 which also extends to a point within convenient reach of the operator. i

Mounted on the inner sidesof the lower sections7 of the casings are oil pans 37 which contain a suitable poison or insecticide to receive and destroy the insects. 'These pans 37 are open at the top but suitable screens 38 eXtend over the same to prevent the fiowersfrom falling into the pans. Guides 39' are- Secured at the :forward sides of the lower portion's 7 to dir'ect'the flowers or plants between the oil pans 37.

The machine is drawn along the row and so ,as to' straddle the row of cotton stalks or plants, either by self-propelled mechanism or otherwise, and the cotton stalks are directed V by the guides 30 first between the elbows 27, .Wherethey are sprayed with an insecticide through thenozzles 32 and the air discharged from the fans through said elbows. Further movement of the machine causes the stalks to be guided by the guides 39 between the oil pans37 and at least some of the boll weevils or insects fall from the plants into the pans through the screens 38.

The flowers or portionsof the cotton or stalks that have become'dislodged and have 'fallen to the ground are collect'ed by the col-' i lectors ll and the suction created therein by 'the fans and drawn through the fans and the 3 tubes 22 and, discharged into the receptacles' 24:,fromjwhere they may be removed' for destruction either by burning or otherwise. The force of the fans also acts through the baffles 28 and the elbows 27 to enhance the' spraying action of the insecticide from the nozzles 32, which insecticide is supplied from the tanks 34, the supply being regulated by the valves 35 and levers 36, from within con` venient reach of the operator.
